FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

I was following your quickstart guide. I added everything correctly. But when I run the yarn start command it is giving me a heap out of memory error.

Here is the full error code.

Thanks for the report @rgtstha We are aware of this and currently looking into how to solve it.

For now, you can set the react-scripts dependency to ^4.0.3 which seems to solve the issue.

It has started since create-react-app has updated that dependency by default.

If anyone has any idea on how to solve the issue please let me know! Increasing the heap size does not help. Something seems to leak memory I’m the build process

You’re right, thanks a lot! Love your work, great quality of code. Actually urge me on writing TS.
